OSHKOSH – Personnel records of two officers involved in fatally shooting a suspect July 31 show neither had been disciplined and both had been commended during their years with the Oshkosh Police Department.

On Tuesday, Oshkosh Police released records detailing the work histories of Aaron Achterberg and Kyle Roberts, who remain on paid administrative leave in the aftermath of the death of 28-year-old Isaiah Tucker . USA TODAY NETWORK-Wisconsin obtained the files through an open records request.

The files show a clean work history, though the department declined to release performance evaluations, citing an exemption in open records law. Achterberg has worked for the department for nine years, while Roberts has worked in Oshkosh for six years.

Both officers are still on paid leave "until further notice," documents show.

Investigation nearing end

The inquiry into the incident in which Tucker was killed is nearly completed, authorities said.

The incident began in the early hours of July 31, when Achterberg and Roberts responded to a pair of calls accusing Tucker of trying to take items from a home in the 300 block of Knapp Street, where he lived as recently as May.

When the officers arrived, Tucker drove a car through the garage door before getting the car stuck in the yard. While one officer tried to pull Tucker out of the vehicle, he sped toward the other officer, police say.

Either Achterberg or Roberts then fired at the vehicle as Tucker accelerated. Police have not said who shot at Tucker, or who tried to pull him from the car. Tucker died in a hospital that morning after officials found him wounded and hiding in a shed blocks away. His car was found wrecked in the 800 block of West Sixth Avenue.

The shooting brought pleas for more information from family and friends, who gathered for a vigil at the Knapp Street home on Aug. 5.

A Wisconsin Department of Justice Division of Criminal Investigation inquiry into the shooting is completed, though the agency is waiting to compile a coroner's report and other information, said DCI spokesman Johnny Koremenos. The agency has turned over its report on the shooting to the Winnebago County District Attorney's office.

DCI will likely release its investigation into the shooting next week, Koremenos said, after the district attorney's office decides if it will bring criminal charges in the case.

Winnebago County District Attorney Christian Gossett said investigators worked quickly to complete the report. His office will announce its decision after it reviews the reports and speaks with Tucker's family, he said.

"Our focus is of course on getting it right, but everyone is sensitive to the fact that these are cases that can impact the community," Gossett said. "We've all seen what happens when that isn't the case."

Work history

Achterberg and Roberts received department honors for saving lives as recently as last fall.

Achterberg earned the police department’s Distinguished Service Medal for pulling a father from a frozen lake in December 2011, as he was trying to save his drowning 15-year-old son. Roberts received a Lifesaving Award in September 2016 after he prolonged an 85-year-old man's life that April by performing CPR.

Achterberg is an Eau Claire native who graduated from the University of Wisconsin-Stevens Point in 2006. He worked part-time at police departments in River Falls, Ellsworth and Stanley before joining the Oshkosh department in 2008.

Originally from Brown Deer, Roberts graduated from the University of Wisconsin-Eau Claire in December 2010, where he earned a degree in criminal justice and minored in psychology, records show. He joined the Oshkosh Police Department in April 2011.

He served as a combat engineer and team leader in the Wisconsin Army National Guard from March 2005 to 2010, and was promoted to sergeant in 2010. Roberts was deployed to Afghanistan from 2008 to 2009, and was awarded the Bronze Star and Purple Heart, according to his resume.

The Eau Claire Leader-Telegram reported in August 2010 that members of Roberts' unit, the 951st Engineer Company, were awarded the Valorous Unit Award, the second-highest Army unit declaration. Roberts' enlistment ended in 2011, according to the report.

Roberts leaned on his military experience in his application to work for Oshkosh Police, records show.

"My education has taught me to learn and communicate effectively," Roberts wrote in his police department application in 2010, "while my military experience has taught me how to lead and make effective decisions in dangerous and stressful situations."
